Erik Krogen commented on HDFS-12746: ------------------------------------ Thanks for the feedback [~anu]! I agree with you about logging all commands; this is pretty much what I had in mind. I'm not sure about machine readable. Did you have something specific in mind? I was thinking that this should follow the format of the other audit logs, e.g. a set of a key-value pairs separated by equals. But maybe this is a good opportunity to develop something better; the lack of easily parseable format on the NN's audit logs has been an annoyance for quite some time. > DataNode Audit Logger > --------------------- > > Key: HDFS-12746 > URL: https://issues.apache.org/jira/browse/HDFS-12746 > Project: Hadoop HDFS > Issue Type: Improvement > Components: datanode, logging > Reporter: Erik Krogen > > I would like to discuss adding in an audit logger for the Datanodes.
